In recent years,the incidence and mortality rates of hepatocellular carcinoma in China have gradually become close to each other,reflecting persistent limitations in current diagnostic and therapeutic strategies.Given the close association between hepatocellular carcinoma development and the progression of precancerous lesions,the expert panel released the first edition of the Multidisciplinary Experts Consensus on Diagnosis and Treatment of Precancerous Lesions of Hepatocellular Carcinoma in 2020 and updated it in 2023,aiming to advance early-intervention strategies and improve overall patient survival rates.This article provides an in-depth interpretation of the key imaging diagnostic points outlined in the consensus,aiming to offer radiologists at all levels with a robust reference for early identification and diagnosis of hepatocellular carcinoma precancerous lesions,thereby facilitating critical support for timely patient intervention and treatment.

As a globally prevalent malignancy with high morbidity and mortality rates,hepatocellular carcinoma has demonstrated significant potential in prognostic prediction and therapeutic evaluation through its imaging manifestations.This article focuses on the potential correlations between current imaging characteristics of hepatocellular carcinoma and its prognosis,emphasizing the importance of adopting and promoting a standardized imaging terminology system.It illustrates specific examples of imaging features associated with prognosis,reviews recent research hotspots and advancements in hepatocellular carcinoma prognosis.The aim is to offer precise prognostication,diagnosis and treatment strategies for patients with hepatocellular carcinoma.

Hepatocellular carcinoma(HCC)is categorized into two major classes based on the heterogeneity of histological phenotypes:proliferative HCC and non-proliferative HCC.These classes exhibit distinct clinical,molecular and imaging characteristics.Within these two major categories,there exist multiple pathological subtypes,each demonstrating unique molecular and histological features that manifest differently in imaging findings.Additionally,the prognosis of these HCC pathological subtypes diverges from that of not-otherwise-specified HCC,and current clinical guidelines for their treatment remain unclear.This article aims to summarize the imaging manifestations and prognosis of the histopathological subtypes of HCC,so as to enhance identification and judgement of HCC subtypes,and to provide a theoretical basis for selecting appropriate therapeutic strategies.

In clinical practice,the diagnosis of hepatocellular carcinoma primarily relies on imaging findings.For cases with atypical imaging features or insufficient diagnostic specificity,pathological analysis remains essential.With the advancement of precision medicine,research focus has expanded from pure diagnostic evaluation to therapeutic efficacy prediction.Imaging-based prognostic biomarkers have emerged as a key research frontier in hepatocellular carcinoma management.Although accurate diagnosis remains paramount,current investigations increasingly prioritize the identification of biomarkers for treatment response prediction and outcome stratification.Recent studies demonstrate that radiological characteristics not only reflect tumor heterogeneity but also carry prognostic implications for hepatocellular carcinoma.These imaging biomarkers enable non-invasive outcome prediction and provide objective evidence to optimize therapeutic decision-making.This comprehensive review summarizes MRI-derived imaging features associated with hepatocellular carcinoma prognosis,aiming to guide personalized treatment strategies and ultimately improve survival outcomes for hepatocellular carcinoma patients.
